i40e/base: avoid unwanted Tx traffic mirroring

In Multi-Function Mode (MFP) particularly when the PF VSI is set
in limited promiscuous mode, the HW switch was still mirroring the
outgoing packets from other VSIs (VF/VMdq) onto the PF VSI.

This sets a new bit to avoid above mirroring, and it is in limited
promiscuous on the PF VSI in MFP which is similar to default port
VSI.
